BEST MODE
Hereinafter, the present invention will be described in detail with
reference to the drawings.
As used herein, the suffixes "module" and "unit" are added or used
interchangeably to facilitate preparation of this specification and
are not intended to suggest distinct meanings or functions.
Accordingly, the terms "module" and "unit" may be used
interchangeably.
FIG. 1 is a configuration diagram illustrating an audio output
system according to an embodiment of the present invention.
Referring to the figure, an audio output system 10 according to an
embodiment of the present invention may include an audio output
device 100, an AP device 400, and a mobile terminal 600.
The audio output system 10 may further include an image display
device 500 and a server 300.
The audio output device 100 may transmit a repeated wireless signal
to the outside, receive audio data from the mobile terminal that
receives the repeated wireless signal, and output sound
corresponding to the received audio data.
The repeated wireless signal may be a wireless signal based on BLE
(BLUETOOTH LOW ENERGY).
The audio data may be received using a communication scheme other
than BLE. For example, the audio data may be received using a
communication scheme such as Wi-Fi, Wi-Fi Direct, or DLNA.
The audio output device 100 may be connected to the AP device 400
in a wired or wireless manner. The audio output device 100 may
exchange data with the server 300 through the AP device 400 over
the network 530.
The audio output device 100 may store information on the output
audio data. In particular, the audio output device 100 may store a
list of music files reproduced and output. Then, at least a part of
the music file list may be transmitted to the server 300.
Meanwhile, the audio output device 100 may be connected to the
video display device 500 such as a TV in wired or wireless manner,
and may output sound corresponding to the audio data received from
the video display device 500.
The server 300 may store at least a part of the music file list.
Then, the server 300 may classify the received music file list by
mood. and the server 300 may transmit the mood information on the
music files to the audio output device 100.
The mobile terminal 600 receives a repeated wireless signal from
the audio output device 100 and wirelessly transmits the audio data
to the audio output device 100 if the strength or level of the
repeated wireless signal is greater than or equal to a first
predetermined value.
Particularly, during audio reproduction, audio data may be
wirelessly transmitted to the audio output device 100 if the
strength or level of the repeated wireless signal received is
greater than or equal to the first predetermined value.
At this time, while audio reproduction is maintained by the mobile
terminal 600, the audio data to be reproduced may be output to the
outside through the second communication module 615b instead of the
sound output unit 653 in the mobile terminal 600.
For example, the mobile terminal 600 may receive a repeated beacon
signal of the BLE scheme from the audio output device 100, and
wirelessly transmit the audio data being reproduced to the audio
output device 100 if the received signal strength indicator (RSSI)
of the beacon signal is greater than or equal to the first
predetermined value.
The beacon signal may include device information on the audio
output device. Alternatively, the device information may be
transmitted to the outside together with the beacon signal.
Accordingly, the mobile terminal 600 may transmit the audio data
being reproduced to the audio output device 100 corresponding to
the device information.
FIG. 2 illustrates an example of deployment of the audio output
device of FIG. 1.
Referring to the figure, a plurality of audio output devices 100a,
100b, 100c, 100d, and 100e may be disposed in a building 40.
In particular, the plurality of audio output devices 100a, 100b,
100c, 100d, and 100e may be disposed on the same network by the AP
device 400 in FIG. 1. The plurality of audio output devices 100a,
100b, 100c, 100d, and 100e may exchange data.
For example, if the distance from the first audio output device
100a is shortened and thus the RSSI of the beacon signal from the
first audio output device 100a becomes greater than or equal to the
first predetermined value while the mobile terminal 600 reproduces
and outputs music, the mobile terminal 600 may wirelessly transmit
the audio data to the first audio output device 100a. Thereby, the
sound corresponding to the audio data may be output from the first
audio output device 100a.
Thereafter, if the distance between the mobile terminal 600 and the
second audio output device 100b is shortened and thus the RSSI of
the beacon signal from the second audio output device 100b is
greater than or equal to the first predetermined value, the mobile
terminal 600 may wirelessly transmit the audio data to the second
audio output device 100b. Thus, the sound corresponding to the
audio data may be output from the second audio output device 100b.
Thereby, seamless sound output may be provided.
FIG. 3 is an exemplary internal block diagram illustrating the
audio output device of FIG. 1.
Referring to the figure, the audio output device 100 may include a
communication unit 110 for communication with other external
devices, an input unit 120 for user input, a memory 140, a
controller 170 for internal control, an audio output unit 185 to
output sound, a microphone 187 to collect sound, and a power unit
190.
The communication unit 110 may include a first communication module
111 to transmit a repeated wireless signal to the outside, a second
communication module 112 to receive audio data from the mobile
terminal 600 and the like, and a third communication module 113 to
exchange data with the AP device.
The first communication module 111 may be, for example, a
communication module for Bluetooth communication. In particular, it
may be a BLE-based communication module. For example, the first
communication module 111 may repeatedly output a BLE-based beacon
signal. Here, repetition of the beacon signal may be performed
periodically.
The first communication module 111 based on BLE may be driven even
at low power, and may be implemented as a separate detachable unit.
In addition, the first communication module 111 can be driven for a
long time even using a separate internal battery.
Meanwhile, the first communication module 111 may operate in a
single mode, in which only BLE-based communication is allowed, or
in a dual mode in which BLE-based communication and Bluetooth
communication are allowed.
If the RSSI of the beacon signal from the first communication
module 111 in the audio output device 100 is greater than or equal
to the first predetermined value, the mobile terminal 600 may
transmit the beacon signal to the audio output device 100,
particularly, the second communication module 112. At this time,
the device information on the mobile terminal 600 may also be
transmitted.
Meanwhile, the second communication module 112 may be, for example,
a communication module for Wi-Fi communication. Therefore, the
bandwidth in the communication scheme of the second communication
module 112 may be larger than the bandwidth in the communication
scheme of the first communication module 111.
The first communication module 111 based on Bluetooth may not be
capable of transmitting/receiving a large amount of audio data due
to bandwidth limitation. Therefore, in order to transmit/receive
audio data having a good sound quality, the Wi-Fi-based second
communication module 112 having a larger bandwidth than the first
communication module 111 is preferably used.
That is, the second communication module 112 may receive audio data
from the mobile terminal 600. The device information of the mobile
terminal 600 may also be received.
The third communication module 113 may be a communication module
for Ethernet communication. Accordingly, the third communication
module 113 may perform wired data exchange with the AP device
400.
The memory 140 may store a list of music files. For example, when a
plurality of electronic devices is shared on the same network with
respect to the AP device 400, the memory 140 may store a list of
music files stored in each electronic device.
The list of music files may be received via the second
communication module 112.
The third communication module 113 may transmit the music file list
related information to the server 300 via the AP device 400 and the
network 530, and receive mode information about each music file
from the server 300.
The controller 170 may control each unit in the audio output device
100.
Specifically, the controller 170 may perform a control operation
through the communication unit 110 such that a repeated wireless
signal is output. In addition, the controller 170 may control the
repeated wireless signal to be repeated at regular intervals.
Further, the controller 170 may control the level of the repeated
wireless signal to be constant.
In outputting the sound from the audio output unit 185, the
controller 170 may control the set volume information to be
transmitted to the mobile terminal 600 through the second
communication module 112 in order to meet the balance of volume
with the volumes of the other audio output devices.
The controller 170 may reproduce the audio data received through
the second communication module 112, and control the audio data to
be output through the audio output unit 185.
The controller 170 may control a sound with the volume varied to be
output in reproducing the audio data, according to a volume
adjustment signal from the mobile terminal 600.
The audio output unit 185 receives the audio data, i.e., the
electrical signal, signal-processed by the controller 170, converts
the audio data into an audio signal, and outputs the audio signal.
That is, it outputs sound corresponding to the audio data. To this
end, the audio output unit 185 may include a speaker having an
internal circuit or the like. For example, a plurality of speakers
may be provided internally to output sound of a plurality of
channels.

first communication module of FIG. 3.
Referring to the figure, the first communication module 111 may be
a low power based BLE communication module. The first communication
module may be detached from or attached to the periphery of various
electronic devices.
Accordingly, the first communication module 111 may include a
transmission/reception unit 210 capable of transmitting or
receiving data according to a BLE-based communication scheme, an
interface unit 230 for exchange of data with the controller 170, a

Alternatively, it may receive a Bluetooth-based pairing signal from
an external electronic device.
The memory 240 may store channel frequency information for
outputting the beacon signal, level information on the beacon
signal, and the like. In addition, the memory may store a pairing
request signal or the like received from the outside.
The processor 270 controls operations of the first communication
module 111 and the like. For example, using the frequency channel
information and the level information on the beacon signal stored
in the memory 240, the processor 270 may change the frequency
channel of the beacon signal output from the first communication
module 111 or control the level of the signal to be constant.
The power supply 290 may supply power to internal units such as the
transmission/reception unit 210 to transmit a repeating wireless
signal, that is, a beacon signal Sbe to the outside.
The power supply 290 may include an internal battery when the first
communication module 111 is configured as a separate detectable or
attachable unit.
FIG. 5 illustrates an example of a repeated wireless signal output
from the first communication module of FIG. 3.
Referring to the figure, a repeated wireless signal may be a
BLE-based beacon signal Sbe.
This beacon signal Sbe may be repeated like Sbe1 and Sbe2, and may
be repeated with a period of Tbe.
FIG. 6 is an internal block diagram illustrating the mobile
terminal of FIG. 1.

input unit 630, a sensing unit 640, an output unit 650, a memory
660, an interface unit 670, a controller 680, and a power supply
690.
The wireless communication unit 610 may include a broadcast
reception module 611, a mobile communication module 613, a wireless
communication module 615, and a GPS module 619.
The broadcast reception module 611 may receive at least one of a
broadcast signal and broadcast related information from an external
broadcast management server on a broadcast channel. The broadcast
channel may include a satellite channel and a terrestrial
channel.
The broadcast signal and/or broadcast related information received
through the broadcast reception module 611 may be stored in the
memory 660.
The mobile communication module 613 transmits and receives a
wireless signal to and from at least one of a base station, an
external terminal, and a server over a mobile communication
network. Here, the wireless signal may include a voice call signal,
a video call signal, or various types of data according to
transmission/reception of a text/multimedia message.
The wireless communication module 615 is a module for wireless
communication and may be built in or externally attached to the
mobile terminal 600. For example, the wireless communication module
615 may include a first communication module 615a for Bluetooth
communication, particularly BLE-based Bluetooth communication, and
a second communication module 615b for Wi-Fi-based wireless
communication or Wi-Fi Direct-based wireless communication.
In addition, radio frequency identification (RFID), infrared data
association (IrDA), ultra-wideband (UWB), ZigBee, or the like may
be used as the short distance communication technology.
The global positioning system (GPS) module 619 may receive position
information from a plurality of GPS satellites.
The audio/video (A/V) input unit 620 is provided for inputting an
audio signal or a video signal, and may include a camera 621 and a
microphone 623.
The user input unit 630 generates key input data that the user
inputs to control the operation of the terminal. To this end, the
user input unit 630 may include a key pad, a dome switch, and a
touch pad (resistive pad/capacitive pad). Particularly, when the
touch pad and the display 651 form a layered structure, the
structure may be called a touchscreen.
The sensing unit 640 may generate a sensing signal for controlling
operation of the mobile terminal 600 by sensing the current state
of the mobile terminal 600 such as the open/closed state of the
mobile terminal 600, the position of the mobile terminal 600, and
contact of the user.
The sensing unit 640 may include a haptic sensor 641, a pressure
sensor 643 and a motion sensor 645. The motion sensor 645 may
employ an acceleration sensor, a gyro sensor, a gravity sensor and
the like to sense movement or location of the mobile terminal. In
particular, the gyro sensor, which is used to measure angular
speed, may sense orientation (angle) of the mobile terminal with
respect to a reference direction.
The output unit 650 may include a display 651, a sound output unit
653, an alarm unit 655, and a haptic module 657.
The display 651 outputs and displays information processed by the
mobile terminal 600.
When the display 651 forms a layered structure with the touchpad to
implement a touchscreen as described above, the display 651 may be
used not only as an output device but also as an input device for
input of information according to user touch.
The sound output unit 653 outputs audio data received from the
wireless communication unit 610 or stored in the memory 660. The
sound output unit 653 may include a speaker and a buzzer.
The alarm unit 655 outputs a signal for reporting occurrence of an
event in the mobile terminal 600. For example, the alarm unit 655
may output a signal in the form of vibration.
The haptic module 657 generates various haptic effects which may be
felt by the user. A typical example of the haptic effects generated
by the haptic module 657 is vibration.
The memory 660 may store a program for processing and control of
the controller 680, and function to temporarily store input data or
output data (e.g., a phonebook, a message, a still image, a moving
image, etc.).
The interface unit 670 serves as an interface for all devices
connected to the mobile terminal 600. The interface unit 670 may
receive data or power from external devices and transfer the same
to the internal constituents of the mobile terminal 600, and allow
the data in the mobile terminal 600 to be transmitted to external
devices.
The controller 680 typically controls operations of the
aforementioned respective elements, thereby controlling overall
operation of the mobile terminal. For example, the controller 680
may perform control or processing related to voice communication,
data communication, video communication, and the like. The
controller 680 may also include a multimedia playback module 681 to
reproduce multimedia. The multimedia playback module 681 may be
provided in the controller 680 as hardware or may be configured
separately from the controller 680.
The power supply 690 supplies power necessary for operations of the
respective constituents according to control of the controller 680
when external power or internal power is applied thereto.
The block diagram of the mobile terminal 600 shown in FIG. 6 is
simply illustrative. The respective constituents of the block
diagram may be integrated, added or omitted according to the
specifications of the mobile terminal 600. That is, two or more
constituents may be combined into one constituent, or one
constituent may be subdivided into two or more constituents, when
necessary. In addition, the functions performed in each block are
simply illustrative, and it should be noted that specified
operations or devices of the blocks do not limit the scope of the
present invention.
FIG. 7 is a flowchart illustrating an exemplary operation of an
audio output system according to an embodiment of the present
invention. FIGS. 8A to 28B illustrate operation of the audio output
system of FIG. 7.
First, referring to FIG. 7, when an audio reproduction input is
provided (S705), the mobile terminal 600 reproduces and outputs the
audio data (S710).
For example, the mobile terminal 600 may reproduce and output an
audio file stored therein or an audio file received through
external streaming, according to a user input or the like. In
particular, the mobile terminal 600 may output sound through the
sound output unit 653.
The audio output device 100 including the first communication
module 111 based on BLE, which may be driven at low power, may
repeatedly transmit a beacon signal Sbe to the outside (S715).
The mobile terminal 600 receives the beacon signal Sbe (S720).
Then, the mobile terminal 600 measures the RSSI of the received
beacon signal, and determines whether the RSSI is greater than or
equal to a first predetermined value (S725). That is, it is
determined whether the strength or level of the beacon signal is
greater than or equal to the first predetermined value.
If the strength or level of the beacon signal is greater than or
equal to the first predetermined value, the mobile terminal 600
transmits audio data being reproduced to the outside through the
second communication module (S730).
At this time, the controller 680 of the mobile terminal 600 may
control reproduction of the audio data to be maintained, but
control the reproduced audio data to be output through the second
communication module 615b, not through the sound output unit 653 in
the mobile terminal 600.
Meanwhile, the audio output device 100 receives the audio data from
the mobile terminal 600 through the second communication module,
which is based on Wi-Fi (S732). Then, the audio output device 100
outputs sound corresponding to the received audio data through the
audio output unit 185 (S735)
Here, the controller 170 of the audio output device 100 may
signal-process the received audio data and transmit an electrical
signal corresponding to the signal-processed audio data to the
audio output unit 185.
Alternatively, the controller 170 of the audio output device 100
may bypass separate signal processing and transmit the received
audio data to the audio output unit 185.
As a result, the user can seamlessly listen to the audio data
reproduced by the mobile terminal 600 through the sound output from
the audio output device 100. Thereby, music may be appreciated
through the audio output device 100, which provides better sound
output, and thus user convenience may be increased.
FIG. 8A illustrates a case where a music file reproduction screen
810 is displayed on the mobile terminal 600.
The controller 680 of the mobile terminal 600 may drive an
application for reproduction of a music file by user input or the
like and control a music file reproduction screen 810 as shown in
the figure to be displayed.
The music file reproduction screen 810 may further include an image
related to a reproduced music file, a play item (pause item), a
previous item, a next item, and a volume adjustment item.
In the figure, it is illustrated that the reproduced music file is
output as a predetermined sound 820 through the sound output unit
653. Unlike the example of the figure, the reproduced music file
may be output as a predetermined sound through headphones or
earphones (not shown).
FIG. 8B illustrate a case where the distance between the mobile
terminal 600 and the audio output device 100 is approximately a
first distance.
The audio output device 100 may repeatedly output a BLE-based
beacon signal as described above.
As shown in the figure, when the distance between the mobile
terminal 600 and the audio output device 100 is approximately the
first distance at a first time, the audio output device 100 may
wirelessly output the signal Sbe1 among the beacon signals.
The controller 680 of the mobile terminal 600 receives Sbe1 through
the first communication module 815a and calculates the RSSI of
Sbe1. Then, the controller determines whether or not the RSSI of
Sbe1 is greater than or equal to a first predetermined value. The
controller 680 may reproduce the audio data being reproduced
without any separate data transfer if the RSSI is less than the
first predetermined value.
FIG. 8C illustrates a case where the distance between the mobile
terminal 600 and the audio output device 100 is approximately a
second distance shorter than the distance of FIG. 8B.
The audio output device 100 may repeatedly output a BLE-based
beacon signal as described above.
As shown in the figure, when the distance between the mobile
terminal 600 and the audio output device 100 is approximately the
second distance at a second time, the audio output device 100 may
output the signal Sbe2 among the beacon signals of FIG. 5.
The controller 680 of the mobile terminal 600 receives Sbe2 through
the first communication module 815a and calculates the RSSI of
Sbe2. Then, the controller determines whether or not the RSSI of
Sbe2 is greater than or equal to the first predetermined value.
If the RSSI is greater than or equal to the first predetermined
value, the controller 680 may perform a control operation through
the second communication module 815a to transmit the audio data for
reproduction. In particular, the audio data being reproduced may be
controlled to be transmitted after the time when the RSSI is
determined to be greater than or equal to the first predetermined
value.
FIG. 8D illustrates a case where audio data Sau is output from the
mobile terminal 600 and a sound 822 corresponding to the received
audio data is output by the audio output device 100.
The controller 170 of the audio output device 100 receives the
audio data and transmits the received audio data to the audio
output unit 185. Accordingly, the audio output unit 185 outputs the
sound 822 corresponding to the audio data.
The controller 170 of the audio output device 100 may repeatedly
output a BLE-based beacon signal in outputting the sound.
Alternatively, the controller 170 of the audio output device 100
may control the BLE-based beacon signal not to be output any longer
in outputting the sound.
The controller 170 may configure transmission or non-transmission
of the beacon signal according to user setting in outputting the
sound.
Even if the distance between the mobile terminal 600 and the audio
output device 100 increases after the mobile terminal 600 transmits
the audio data to the audio output device 100, the audio data may
continue to transmit the audio data to the audio output device
100.
For example, the controller 680 of the mobile terminal 600 may not
perform RSSI calculation on the beacon signal after the audio data
is transmitted.
As another example, after the audio data is transmitted, the
controller 680 of the mobile terminal 600 may perform RSSI
calculation on the beacon signal, and may not transmit the audio
data to the audio output device 100 only when the RSSI is less than
or equal to a second predetermined value, which is less than or
equal to the first predetermined value.
In other words, if the RSSI is greater than the second
predetermined value, the audio data may be continuously transmitted
to the audio output device 100.
FIG. 9A illustrates a beacon signal RSbe1 received by the mobile
terminal 600 when the distance between the mobile terminal 600 and
the audio output device 100 is approximately the first distance as
in FIG. 8B.
Referring to the figure, it is illustrated that the peak level LE1
of the beacon signal RSbe1 received by the mobile terminal 600 is
less than a first predetermined value ref1.
If the peak level LE1 of the received beacon signal RSbe1 is less
than the first predetermined value ref1, the controller 680 of the
mobile terminal 600 outputs sound through the sound output unit
653, rather than outputting the audio data being reproduced to the
audio output device 100.
FIG. 9B illustrates a beacon signal RSbe2 received from the mobile
terminal 600 when the distance between the mobile terminal 600 and
the audio output device 100 is approximately a second distance
shorter than the first distance as in FIG. 8C.
Referring to the figure, it is illustrated that the peak level Le2
of the beacon signal RSbe2 received by the mobile terminal 600 is
greater than the first predetermined value ref1.
If the peak level Le2 of the received beacon signal RSbe2 is
greater than the first predetermined value ref1, the controller 680
of the mobile terminal 600 transmits the reproduced audio data to
the audio output device 100 without outputting the same through to
the sound output unit 653. Then, the audio output device 100
outputs sound corresponding to the received audio data.
In brief, the peak level of the beacon signal RSbe received by the
mobile terminal 600 is approximately inversely proportional to the
distance between the mobile terminal 600 and the audio output
device 100.
Accordingly, if the mobile terminal 600 approaches the audio output
device 100 within a predetermined distance and the peak level of
the received beacon signal is greater than or equal to the first
predetermined value, the mobile terminal 600 transmits the audio
data being reproduced to the audio output device 100, and the audio
output device 100 outputs the sound corresponding to the received
audio data.
The mobile terminal 600 or the audio output device 100 may adjust
the volume of sound output from the audio output device 100
according to the distance between the mobile terminal 600 and the
audio output device 100. Details will be described with reference
to FIGS. 10A to 13C.
FIG. 10A illustrates output of sound 822 of a first volume from the
audio output device 100 while the distance between the mobile
terminal 600 and the audio output device 100 is approximately a
second distance.
The second communication module 112 of the audio output device 100
receives audio data from the mobile terminal 600.
The controller 170 of the audio output device 100 controls the
volume of the sound output from the audio output unit 185 according
to the strength or level of the received audio data.
For example, the controller 170 of the audio output device 100
controls the volume of the sound output from the audio output unit
185 to increase as the strength or level of the received audio data
is lowered.
FIG. 11A illustrates an audio data signal RSau1 received from the
audio output device 100 when the distance between the mobile
terminal 600 and the audio output device 100 is approximately the
second distance as in FIG. 10A.
Referring to the figure, it is illustrated that the level of the
audio data signal RSau1 received by the audio output device 100 is
higher than a reference level refa.
The controller 170 of the audio output device 100 controls the
sound corresponding to the received audio data to be continuously
output if the level of the received audio data is higher than the
reference level refa. Meanwhile, the controller 170 of the audio
output device 100 controls the sound 822 of the first volume to be
output according to the level of the received audio data signal
RSau1, as shown in FIG. 10A.
FIG. 10B illustrates output of a sound 823 of a second volume
higher than the first volume from the audio output device 100 while
the distance between the mobile terminal 600 and the audio output
device 100 is approximately a first distance longer than the second
distance.
FIG. 11B illustrates an audio data signal RSau2 received by the
audio output device 100 when the distance between the mobile
terminal 600 and the audio output device 100 is approximately the
first distance as shown in FIG. 10B.
Referring to the figure, it is illustrated that the level of the
audio data signal RSau2 received by the audio output device 100 is
higher than the reference level refa.
The controller 170 of the audio output device 100 controls the
sound corresponding to the received audio data to be continuously
output if the level of the received audio data is higher than the
reference level refa. The controller 170 of the audio output device
100 controls the sound 823 of the second volume, which is higher
than the first volume, to be output according to the level of the
received audio data signal RSau2, as shown in FIG. 10B.
FIG. 10C illustrates a case where no sound is output from the audio
output device 100 while the distance between the mobile terminal
600 and the audio output device 100 is approximately a third
distance longer than the first distance.
FIG. 11C illustrates an audio data signal RSau3 received from the
audio output device 100 when the distance between the mobile
terminal 600 and the audio output device 100 is approximately the
third distance as shown in FIG. 10C.
Referring to the figure, it is illustrated that the level of the
audio data signal RSau3 received by the audio output device 100 is
lower than the reference level refa.
The controller 170 of the audio output device 100 controls the
sound corresponding to the received audio data not to be output if
the level of the received audio data is lower the reference level
refa.
FIG. 10D illustrates a case where the volume of the sound output
from the audio output device 100 at distance D1 is VOL 2 and the
volume of the sound output from the audio output device 100 at
distance D2 longer than distance D1 is VOL 7 when the user 50 moves
the mobile terminal 600.
In this case, the audio output device 100 continues to output a BLE
based repeated beacon signal Sbe.
Adjustment of the volume of the audio output device 100 according
to the distance may be controlled by the mobile terminal 600,
rather than the audio output device 100. Details will be described
with reference to FIG. 12A to 13C.
FIG. 12A illustrates a case where the audio output device 100
outputs a beacon signal Sbe2 and the mobile terminal 600 transmits
an audio data signal Sau1 to the audio output device 100 in
response to the beacon signal when the distance between the mobile
terminal 600 and the audio output device 100 is approximately the
second distance. In this case, the audio output device 100 may
output the sound 822 of the first volume.
FIG. 13A illustrates a beacon signal RSbe2 received by the mobile
terminal 600 when the distance between the mobile terminal 600 and
the audio output device 100 is approximately the second distance as
shown in FIG. 12A.
Referring to the figure, it is illustrated that the level of the
beacon signal RSbe2 received by the mobile terminal 600 is greater
than the first predetermined value ref1.
The controller 680 of the mobile terminal 600 controls sound
corresponding to the received audio data to be output if the level
of the beacon signal RSbe2 received by the mobile terminal 600 is
greater than the first predetermined value ref1.
Specifically, if the level of the received beacon signal RSbe2 is
greater than the first predetermined value ref1, the controller 680
of the mobile terminal 600 may control sound of the first volume to
be output from the audio output device 100.
For example, the controller 680 of the mobile terminal 600 may
further transmit the first volume information and the audio data to
the audio output device 100, based on the received beacon signal
RSbe2.
The controller 170 of the audio output device 100 controls the
sound 822 of the first volume to be output based on the received
first volume information.
FIG. 13B illustrates a beacon signal RSbe3 received by the mobile
terminal 600 when the distance between the mobile terminal 600 and
the audio output device 100 is a first distance longer than the
second distance, as shown in FIG. 12B.
Referring to the figure, it is illustrated that the level of the
beacon signal RSbe3 received by the mobile terminal 600 is less
than the first predetermined value ref1 but greater than the second
predetermined value ref2.
If the level of the received beacon signal RSbe3 is greater than
the second predetermined value ref2, the controller 680 of the
mobile terminal 600 may control sound 823 of a second volume higher
than the first volume of the reproduced audio data to be output
from the audio output device 100.
For example, the controller 680 of the mobile terminal 600 may
further transmit the second volume information and the audio data
to the audio output device 100, based on the RSSI of the received
beacon signal RSbe3.
The controller 170 of the audio output device 100 controls the
sound 823 of the second volume to be output based on the received
second volume information.
FIG. 13C illustrates a beacon signal RSbe4 received by the mobile
terminal 600 when the distance between the mobile terminal 600 and
the audio output device 100 is approximately a third distance
longer than the first distance, as shown in FIG. 12C.
Referring to the figure, it is illustrated that the level of the
beacon signal RSbe4 received by the mobile terminal 600 is less
than the second predetermined value ref2.
If the level of the received beacon signal RSbe4 is less than the
second predetermined value ref2, the controller 680 of the mobile
terminal 600 may control the reproduced audio data not to be
transmitted to the audio output device 100 any longer. Thereby, the
audio output device 100 does not output sound corresponding to the
received audio data any more.
A plurality of audio output devices may be provided in the audio
output system 10 of FIG. 1A or 1B, and various examples of sound
output from the plurality of audio output devices will be described
with reference to FIGS. 14A to 18B.
FIG. 14A illustrates a case where a first audio output device 100a
of the plurality of audio output devices 100a, 100b and 100c
receives audio data reproduced by the mobile terminal 600 and
outputs corresponding sound 820a.
The plurality of audio output devices 100a, 100b, and 100c output
beacon signals Sbea, Sbeb, and Sbec, respectively, which are
repeated.
The beacon signals Sbea, Sbeb, and Sbec may include device
information on each of the plurality of audio output devices 100a,
100b, and 100c. Alternatively, the device information may be
transmitted to the outside together with the respective beacon
signals Sbea, Sbeb, and Sbec.
The mobile terminal 600 may receive the beacon signals Sbea, Sbeb,
and Sbec from the plurality of audio output devices 100a, 100b, and
100c through the first communication module 615a.
For example, the controller 680 of the mobile terminal 600 may
control an audio output device corresponding to the largest RSSI
among the beacon signals Sbea, Sbeb and Sbec to transmit audio data
being reproduced, through the second communication module 812.
Specifically, when receiving one beacon signal, the controller 680
of the mobile terminal 600 may control the audio data being
reproduced to be transmitted to the outside only when the RSSI of
the beacon signal is greater than or equal to a first predetermined
value.
However, when receiving a plurality of beacon signals, the
controller 680 of the mobile terminal 600 may control an audio
output device corresponding to the greatest RSSI to transmit the
audio data being reproduced, regardless of whether the RSSI of one
beacon signal is greater than or equal to the first predetermined
value.
As another example, the controller 680 of the mobile terminal 600
may control the audio data being reproduced to be transmitted to an
audio output device corresponding to a beacon signal whose RSSI is
greater than or equal to the first predetermined value ref1 among
the beacon signals Sbea, Sbeb and Sbec.
In this case, the controller 680 of the mobile terminal 600 may
control the same audio data to be transmitted to the plurality of
audio output devices if the RSSI of the received beacon signal is
greater than or equal to the first predetermined value.
As another example, the controller 680 of the mobile terminal 600
may control the audio data being reproduced to be output to the
outside only when the RSSI of the corresponding beacon signal among
the received beacon signals Sbea, Sbeb, and Sbec is greater than or
equal to the first predetermined value. When there are multiple
beacon signals whose RSSIs are greater than or equal to the first
predetermined value, the reproduced audio data may be controlled to
be transmitted to multiple audio output devices.
Hereinafter, it is assumed that, if the RSSI of the beacon signal
is greater than or equal to a first predetermined value, the
controller 680 of the mobile terminal 600 performs a control
operation to transmit all the audio data being reproduced to the
corresponding audio output device regardless of whether a plurality
of beacon signals or a single beacon signal is received by the
mobile terminal 600.
FIG. 14A may illustrate a case where only the first beacon signal
Sbea output from the first audio output device 100a among the
plurality of beacon signals Sbea, Sbeb, and Sbec has an RSSI
greater than or equal to a first predetermined value, and thus the
mobile terminal 600 transmits audio data Saua to the first audio
output device 100a, and the first audio output device 100a outputs
sound 820a corresponding to the audio data Saua.
Next, FIG. 14B illustrates a case where the second audio output
device 100b among the plurality of audio output devices 100a, 100b
and 100c receives audio data Saub reproduced by the mobile terminal
600 and outputs corresponding sound 820b.
That is, FIG. 14B may illustrate a case where only the second
beacon signal Sbeb output from the second audio output device 100b
among a plurality of beacon signals is greater than or equal to the
first predetermined value, and thus the mobile terminal 600
transmits the audio data Saub to the second audio output device
100b and the second audio output device 100b outputs sound 820b
corresponding to the audio data Saub.
Next, FIG. 14C illustrates a case where the third audio output
device 100c among the audio output devices 100a, 100b and 100c
receives audio data Sauc reproduced by the mobile terminal 600 and
outputs corresponding sound 820c.
That is, FIG. 14C illustrates a case where only the third beacon
signal Sbec output from the third audio output device 100c among
the plurality of beacon signals has a strength greater than or
equal to the first predetermined value, and the mobile terminal 600
transmits the audio data Sauc to the third audio output device 100c
and the third audio output device 100c outputs sound 820c
corresponding to the audio data Sauc.
The plurality of audio output devices 100a, 100b, and 100c may be
grouped together. The grouping information on the plurality of
audio output devices 100a, 100b, and 100c may be stored in one of
the audio output devices 100a, 100b, and 100c.
For example, when the first audio output device 100a among the
audio output devices 100a, 100b, and 100c is a main audio output
device, the memory 140 of the first audio output device 100a may
contain device information on the plurality of audio output devices
100a, 100b and 100c, and the controller 170 may perform a control
operation such that different sounds or the same sound are output
according to audio channel assignment to the audio output devices
100a, 100b and 100c.
FIG. 15A illustrates output of sounds of different channels from
the plurality of audio output devices 100a, 100b, and 100c.
The figure may illustrate that only the first beacon signal Sbea
output from the first audio output device 100a among the plurality
of beacon signals Sbea, Sbeb and Sbec is greater than or equal to
the first predetermined value, and thus the mobile terminal 600
transmits audio data Saua to the first audio output device 100a and
the first audio output device 100a outputs a first sound 820L
corresponding to the audio data Saua.
The controller 170 of the first audio output device 100a may
perform audio channel setting based on the grouping information on
the plurality of audio output devices 100a, 100b, and 100c.
For example, upon receiving the audio data Saua from the mobile
terminal 600, the controller 170 of the first audio output device
100a may perform a control operation such that a left channel sound
820L is output from the first audio output device 100a, a center
channel sound 802c is output from the second audio output device
100b, and a right channel sound 802R is output from the third audio
output device 100c.
To this end, when the audio data Saua is received from the mobile
terminal 600, the controller 170 of the first audio output device
100a may perform a control operation to separate channels for the
audio data Saua to transmit audio data of the left channel among
the separated channels to the audio output unit 185 of the first
audio output device 100a, transmit audio data SauaC of the center
channel among the separated channels to the second audio output
device 100b through the second communication module 112, and
transmit audio data SauaR of the right channel among the separated
channels to the third audio output device 100c through the second
communication module 112.
FIG. 15B illustrates a case where the same sound is output from a
plurality of audio output devices 100a, 100b, and 100c.
The figure illustrates that only the first beacon signal Sbea
output from the first audio output device 100a among the plurality
of beacon signals Sbea, Sbeb, and Sbec has an RSSI greater than or
equal to a first predetermined value, and thus the mobile terminal
600 transmits audio data Saua to the first audio output device
100a, and the first audio output device 100a outputs sound 820a
corresponding to the audio data Saua.
The controller 170 of the first audio output device 100a may
perform a control operation to output the same sound based on the
grouping information on the plurality of audio output devices 100a,
100b, and 100c.
For example, upon receiving the audio data Saua from the mobile
terminal 600, the controller 170 of the first audio output device
100a may perform a control operation such that the audio data Saub
based on the received audio data Saua is transmitted to the second
audio output device 100b through the second communication module
112, and the audio data Sauc based on the received audio data Saua
is transmitted to the third audio output device 100c through the
second communication module 112.
FIG. 15C illustrates output of the same sound and the same volume
from the plurality of audio output devices 100a, 100b, and
100c.
FIG. 15C is nearly the same as FIG. 15B, except that the same
volume is output from the plurality of audio output devices 100a,
100b, and 100c.
Different volume setting values may be set in the audio output
devices 100a, 100b, and 100c.
The first audio output device 100a, which is the main audio output
device, may store volume setting values for the respective audio
output devices 100a, 100b and 100c in the memory 140. The volume
setting value of each of these audio output devices may be received
from each of the audio output devices 100b and 100c through the
second communication module 112.
The first audio output device 100a may transmit the beacon signal
Sbea and the volume setting value Sspg for each of the audio output
devices 100a, 100b, and 100c) to the mobile terminal 600 through
the first communication module 111.
When the mobile terminal 600 transmits the audio data Saua to the
first audio output device 100a, the mobile terminal 600 may also
transmit information about the volume value to be output from each
audio output device.
Thereby, after receiving the audio data Saua and the volume value
information, the controller 170 of the first audio output device
100a may perform a control operation to transmit the audio data
Saua3 and the volume value information vo3 to the second audio
output device 100b and to transmit the audio data Saua2 and the
volume value information vo2 to the third audio output device
100c.
Unlike FIG. 15C, the mobile terminal 600 may not transmit separate
volume value information to the first audio output device 100a, but
the controller 170 of the first audio output device 100a may
perform a control operation to transmit the audio data Saua3 and
the volume value information vo3 to the second audio output device
100b and to transmit the audio data Saua2 and the volume value
information vo2 to the third audio output device 100c in
consideration of the received audio data Saua and a preset volume
setting value for each audio output device.
If the RSSI of the received beacon signal continues to be greater
than or equal to a first predetermined value within a predetermined
time, the controller 680 of the mobile terminal 600 may perform a
control operation to transmit the audio data being reproduced to
each of the audio output devices 100a, 100b and 100c.
FIGS. 16A to 16C illustrate outputting sound from each audio output
device when the RSSI of the received beacon signal continues to be
greater than or equal to a first predetermined value in the mobile
terminal 600 within a predetermined time.
FIG. 16A illustrates a case where only the first beacon signal Sbea
output from the first audio output device 100a among the plurality
of beacon signals Sbea, Sbeb and Sbec is greater than or equal to
the first predetermined value at a first time T1, and thus the
mobile terminal 600 transmits the audio data Saua to the first
audio output device 100a and the first audio output device 100a
outputs sound 820a corresponding to the audio data Saua.
Next, FIG. 16B illustrates a case where the mobile terminal 600
moves close to the second audio output device 100b at a second time
T2, which is within a predetermined time after the first time
T1.
That is, FIG. 16B illustrates that only the second beacon signal
Sbeb output from the second audio output device 100b among the
plurality of beacon signals Sbea, Sbeb and Sbec is greater than or
equal to the first predetermined value at the second time T2, and
thus the mobile terminal 600 transmits the audio data Saub to the
second audio output device 100b and the second audio output device
100b outputs sound 820b corresponding to the audio data Saub.
At this time, the mobile terminal 600 may transmit the audio data
Saua to the first audio output device 100a, and the first audio
output device 100a may transmit the sound 820a corresponding to the
audio data Saua. Here, the sound 820a and the sound 820b may be the
same sound of the same channel.
Next, FIG. 16C illustrates a case where the mobile terminal 600
moves close to the third audio output device 100c at a third time
T3 within a predetermined time after the second time T2.
That is, FIG. 16C illustrates that only the third beacon signal
Sbec output from the third audio output device 100c among the
plurality of beacon signals Sbea, Sbeb and Sbec is greater than or
equal to the first predetermined value at the third time T3, and
thus the mobile terminal 600 transmits the audio data Sauc to the
third audio output device 100c and the third audio output device
100c outputs sound 820c corresponding to the audio data Sauc.
At this time, the mobile terminal 600 may transmit the audio data
Saua and Saub to the first audio output device 100a and the second
audio output device 100b, and the first audio output device 100a
and the second audio output device 100b may output the same sound
820a together.
If the RSSI of the received beacon signal continues to be greater
than or equal to a first predetermined value within a predetermined
time, the controller 680 of the mobile terminal 600 may perform a
control operation to transmit the audio data being reproduced to
each audio output device such that the audio data is distinguished
by channels.
FIGS. 17A and 17B illustrate output of sound from each audio output
device when the RSSI of the received beacon signal continues to be
greater than or equal to a first predetermined value in the mobile
terminal 600 within a predetermined time, such that the sounds are
distinguished by channels.
FIG. 17A illustrates outputting the sound 820a corresponding to the
received audio data Saua from the first audio output device 100a at
time Ta, as in FIG. 16A.
In addition to the beacon signal, the mobile terminal 600 may
receive grouping information on a plurality of audio output
devices.
FIG. 17B illustrates a case where the mobile terminal 600 moves
close to the third audio output device 100c at time Tb, which is
within a predetermined time after time Ta.
If the third beacon signal Sbec in addition to the first beacon
signal Sbea is greater than or equal to the first predetermined
value within a predetermined time, the controller 680 of the mobile
terminal 600 may perform a control operation to transmit audio data
SauR corresponding to the right channel to the third audio output
device 100c. Then, the controller may perform a control operation
to transmit audio data SauL corresponding to the left channel to
the first audio output device 100a.
That is, the first audio output device 100a may receive the audio
data Saua of the stereo channel and output the corresponding sound
820a at time Ta, and then receive audio data SauL of the left
channel and output the corresponding sound 820L at time Tb.
The third audio output device 100c may output sound 820R
corresponding to the audio data SauR corresponding to the right
channel at time Tb. Accordingly, sounds may be output channel by
channel using a plurality of audio output devices.
Meanwhile, the mobile terminal 600 may receive device information
and channel setting information on each of the audio output devices
100a, 100b, and 100c together with or separately from the beacon
signal.
The controller 680 of the mobile terminal 600 may set an audio
channel for each of the audio output devices 100a, 100b, and 100c
based on the device information and the channel setting
information. In addition, as shown in FIG. 17B, the controller may
perform a control operation to output the left channel sound 820L
to the first audio output device 100a and the right channel sound
820R to the third audio output device 100c.
FIGS. 18A and 18B are similar to FIGS. 17A and 17B.
The difference is that channel setting is performed based on motion
information sensed by the mobile terminal 600, rather than based on
the device information on the audio output devices and the channel
setting information received by the mobile terminal 600.
FIG. 18A illustrates that the mobile terminal 600 is rotated
counterclockwise while being positioned near the first audio output
device 100a. The counterclockwise rotation may be sensed by the
motion sensor 645 in the sensing unit 640.
The mobile terminal 600 receives the beacon signal Sbea of the
first audio output device 100a. If the beacon signal is greater
than or equal to a first predetermined value, the controller 680 of
the mobile terminal 600 may perform a control operation to transmit
the left channel audio data SauL to the first audio output device
100a.
Thus, the first audio output device 100a outputs sound 820L
corresponding to the left channel audio data SauL.
Next, FIG. 18B illustrates that the mobile terminal 600 is
positioned close to the third audio output device 100c and rotated
clockwise at time Tb, which is within a predetermined time after
time Ta. The clockwise rotation may be sensed by the motion sensor
645 in the sensing unit 640.
The mobile terminal 600 receives the beacon signal Sbec of the
third audio output device 100c. If the beacon signal is greater
than or equal to the first predetermined value, the controller 680
of the mobile terminal 600 may perform a control operation to
transmit the right channel audio data SauR to the third audio
output device 100c.
Thus, the third audio output device 100c) outputs sound 820R
corresponding to the right channel audio data SauR. The first audio
output device 100a continues to output the sound 820L corresponding
to the left channel audio data SauL.

Specifically, the controller 680 of the mobile terminal 600 may
perform main/sub setting for the plurality of audio output devices
based on the RSSIs of the received beacon signals Sbea, Sbeb, and
Sbec.
For example, if the strength or level of the beacon signal Sbea
from the first audio output device 100a is the highest, the
controller 680 of the mobile terminal 600 may set the first audio
output device 100a as a main audio output device and the second and
third audio output devices 100b and 100c as sub audio output
devices.
As shown in the figure, an object 2412 representing the main audio
output device and objects 2414 and 2416 representing the sub audio
output devices may be displayed on the screen 2410 for main/sub
setting.
The controller 680 of the mobile terminal 600 may perform main/sub
setting for the plurality of audio output devices based on the
RSSIs of the received beacon signals Sbea, Sbeb, Sbec only when the
RSSIs are greater than or equal to a first predetermined value.
FIG. 24B illustrates an example of main/sub setting and channel
setting for a plurality of audio output devices.
Referring to the figure, the controller 680 of the mobile terminal
600 receives beacon signals Sbea, Sbeb, and Sbec and device signals
from a plurality of audio output devices 100a, 100b, and 100c.
The controller 680 of the mobile terminal 600 may perform a control
operation to display a screen 2410 for main/sub setting for the
plurality of audio output devices 100a, 100b, and 100c, according
to reception of the beacon signals Sbea, Sbeb, and Sbec or based on
user input.
Specifically, the controller 680 of the mobile terminal 600 may
perform main/sub setting for the plurality of audio output devices
100a, 100b, and 100c based on the RSSIs of the received beacon
signals Sbea, Sbeb, and Sbec.
For example, if the strength or the level of the beacon signal Sbeb
from the second audio output device 100b is the highest, the
controller 680 of the mobile terminal 600 may set the second audio
output device 100b as a main audio output device and the first and
third audio output devices 100a and 100c as sub audio output
devices.
In the figure, an object 2424 representing the main audio output
device and objects 2422 and 2426 representing the sub audio output

100.
For example, the first communication module 711 may receive a power
on/off signal from the audio output device 100, and the processor
700 may control the light emitting unit 780 to be turned on or off
based on power on/off signal.
As another example, the first communication module 711 may receive
a color change signal from the audio output device 100, and the
processor 700 may control the color of light emitted from the light
emitting unit 780 to change, based on the color change signal.
The first communication module 711 may transmit device information,
state information, and the like on the lighting device 700 to the
audio output device 100.
The first communication module 711 may exchange data with the audio

The power supply 790 supplies power to internal units. To this end,
it may include an AC/DC converter and a DC/DC converter.
The lighting device 700 may perform only Bluetooth communication
without carrying out a communication scheme such as Wi-Fi.
According to this method, since the lighting device 700 receives a
BLE signal from the audio output device 100, which is constantly
powered on, and operates based on the received BLE signal, it is
not necessary to constantly keep communication such as Wi-Fi
activated. Therefore, power consumption may be reduced.
